The ring end ripped off immediately with little effort. Gets the job done once not for extended use

It is a nice tool to have

So I have to run my cat6 7 feet down an insulated basement wall, that means between drywall and the plastic vapor barrier tight from the insulation behind. My electric tape was unthinkable. So I went for this gadget. I tried pushing it from the top, but the angle against the joist above the ceiling made it rip the vapor barrier and go behind the insulation, so I thought, bummer! On a whim I pushed it UP, where the flexible segments would be less stressed improving the angle of penetration... and pushed and pushed and stop... it hit something. I went to the hole above the ceiling and there it was. I never thought something so thin could go so straight up!
I went to the other end to bring the cat6 on top of the tile ceiling and it saved me time by being able to go 4 tiles over at a time (with 4 segments, the other 6 were waiting in the wall).
The only snag (literally) was that the cable got caught against a joist and top of wall and while pulling, one of the attachments with flimsy split ring (think autoshop key ring) totally got deformed. So I used a piece of wire looped around instead of the ring. It worked.
At the wall I used a braided steel cable with a red plastic cone to pull the cat6 and went down the wall without a hitch!!!
To bring the opposite end of the cat6 inside the house through a small hole, I just pushed the pole segment by segment with the wife watching behind a corner TV stand. The pole went up along the corner until it hit the ceiling and then I shook it and it arched nicely for her to catch it. Easy as pie!
Except for that flimsy split ring, it was perfect. The only improvement I would recommend is to include a male to male threaded adapter. It's hard to keep track of female and male threads in the heat of the battle.
All in all, very impressed.
Too much detail, bit I was so happy. In the past I've had to open multiple holes with some damage to the vapor barriers inside insulated walls, and inside the house, moving furniture and what not.

Didn't want cords hanging down from TV. Installed 2 open wall plates. I had to run internet and coaxial cable from the basement through a little bigger than a 1/2 inch hole. Plus, cables from the TV to the outlet. This tool worked perfect. I had plenty of length and different ends worked great. My favorite accessory was the wire that tighten around the cords.

In my contractor days of the past, I had a crazy stick. A single unit that you extend by setting the coupler. So you always have the full length, but can unset the coupler to make it shorter.

This version you have to screw the pieces together, and keep the extra pieces in you pocket so you don't have to get off the latter. I prepped the ceiling in my garage for down lighting this weekend, and was able to run my romex across the internal side of the ceiling no problem with this stick. After a couple of hours, I was able to establish a workflow with this product and got use to how it works. For the price you can't beat it, and it didn't slow my performance down. It's very strong, yet has the right amount of bend. The screws actually was a benefit, because each screw can acts as a rest, to support the rod vertical so it's doesn't slip down the wall, to hold it place as you tie your string onto the leader tape.

I ended up putting this in my tool bag as a permanent member of the my tool team. This tool is not a joke, and actually performs very well. I wish I could find my crazy stick, because I really liked it. But this tool does things my crazy stick couldn't do such as the flexibility of the material.
